Clark Street-Brooklyn Heights is a deep level tunnel station located in what is known as the Clark Street Tubes, the tunnel that brings to 2,3 and the IRT West Side Line between Manhattan and Brooklyn, the station has a single island platform for the two tracked line through the tunnel. The track walls are curved giving the feeling of a tunnel and have extremely hard to see due to poor lighting on the track walls name tablets that say Clark Street-Brooklyn Heights, and extremely hard to see mosaics of sailing ships within the trim-line. Along each track is a line of green columns. The station is one of three on the entire subway system that are only accessible by elevators (the other two are 168 Street and 181 Street on the 1 train in hilly Washington Heights), two staircases lead up from the station platform to a passageway of decent length that leads to the lower elevator landing where three elevators lead up to an upper level that is located at street level, where a bank of turnstiles and token booth is, in the middle of a small shopping arcade beneath the St. George Hotel. The station's two entrances, one along Clark Street and one along Henry Street have awnings on them that say St. George Hotel.
